Call list backup

[FF]

Hi!
It would be very useful if it would be possible to backup my call list, and then to be able to restore it. Can this be solved?
Thank you very much!

Its allready possible to archive the call-list. But its not possible to restore it on the phone, cause i have no write-permissions in this sector

It's a pity it's not possible... Thank you anyway.
